• is it be possible to guess the number of recipients while encrypting? See the message size when having no bcc. #22
• shouldnt we add reply-to to the decipherers too? even if he wont receive the message, he ll get replies. I think this might be ok, try. -> It seems to me the message will be re-encrypted for them.
• Address for representing e-mails? Address(display_name='Aly Sivji', username='alysivji', domain='gmail.com'),
• base64 encoding as default? Should I concern, isn't it automatic or something? (current PROKI sends text as base64 encoded)
• fetch encryption keys of senders
• should I get rid of allowtrust GPG flag?

should I get rid of allowtrust GPG flag?

We can make def gpg(trust_mode) param to handle trust-model=always if needed in the future. It does not seem to me bad if it stays on by default.
